The user wants me to create a single-page web app that visualizes the Lorenz attractor using Three.js. The requirements are:
1. Use the pre-provided three.min.js file (global THREE)
2. Visualize the Lorenz attractor as a glowing 3D butterfly trajectory
3. Draw over time (animated)
4. Include orbit-drag camera controls
5. Everything in one self-contained index.html file with inline CSS and JS

Let me first check if three.min.js exists in the current directory.

Good, three.min.js is present. Now I'll create the index.html file with:
1. Three.js loaded from three.min.js
2. Lorenz attractor visualization with glowing effect
3. Orbit controls (I'll implement simple orbit drag controls since we can't use external libraries)
4. Animated trajectory drawing over time

The Lorenz equations are:
dx/dt = σ(y - x)
dy/dt = x(ρ - z) - y
dz/dt = xy - βz

Classic parameters: σ=10, ρ=28, β=8/3

I'll create a particle trail that follows the Lorenz attractor path and has a glowing appearance.

The file has been created. Let me verify it exists and check its contents briefly.

The file has been created successfully. Let me provide a summary of what was built.
